ROM: CM9 Experimental Build 01062012
Build number: IML74K
What doesn’t work for me:
Some apps – 3G Watchdog, some emulators, etc
MTP file transfer
** Full list of known issues from the developers can be found here **
Some apps (Smart Keyboard, Titanium Backup, Facebook, Gmail, Opera, Whatsapp, Skype, etc)
Restoring apps from Titanium Backup
Having been using this ROM for 2 days, I can conclude that this ROM is indeed stable enough to be used as your daily ROM. Despite the early release alpha status, this ROM will not cause much issues for you (unless you really need the video recording function or the MTP functionality). For me, this isn’t a deal breaker since I don’t really use the video recording function much. As for the MTP function, I can bear with using Bluetooth transfers if needed for now. I do use MTP for saving and transferring files between work and home, but I can live with using a separate flash drive for that in the mean time. When plugging the phone into your PC, you will see the “Installing drivers” message and then it will show up as a MTP device. You can browse the device but copying files in or out is not possible for now.
The ROM looks amazing and it works brilliantly. The CyanogenMod team did a wonderful job with the ROM despite certain obstacles like lack of kernel sources and/or Samsung leaks. I’m sure that given time, say another month or so with the appropriate kernel source releases or leaks, this can and certainly will be a great ROM. The interface looks amazing and very clean. I will not go through the details as they have been covered by sites like Mobile-Review.com (p1 p2) or GSMArena.com and you can read for yourselves. The Galaxy Nexus review also will provide some good idea on what is to be expected.
I’m very impressed and happy with this ROM. There has been no crashes, no sudden reboots and certainly no overheating or battery issues that I’ve seen. the Galaxy SII on CM7.1 was good but on this early release of CM9, the Galaxy SII has went from good to great! I did not try the FaceUnlock feature as I do not require that. I think it is a novelty that people like (the “its something new” syndrome) for now but soon, it may wear off. I prefer the standard methods of unlocking. Therefore, I did not install the FaceUnlock zip when installing this ROM.
Battery life has been pretty standard and comparable with CM7.1 which is good, considering that this ROM is just in experimental stage. With minimal use, it can easily last more than 24 hours. With regular daily use, you’d probably see about 12-16 hours from it (depending on your usage model). This is good enough for me. I don’t mind charging my phone every night.
Installing this is also not much hassle provided you already have CWM installed from a previous ROM (you may want to install something like CM7.1 or Litening ROM prior to installing this).
Summary of installing CM9:
1. Download CM9 zip, GApps 7.1 zip, GApps Fixer zip, FaceUnlock zip
2. Do a SMS backup (I use “SMS Backup & Restore”)
3. Backup your contacts to Google or use a backup application (I use Google backup)
4. Copy over the zips to your device memory
5. Do a Nandroid backup and have a copy of a CWM flashable ROM on your device memory in case something goes wrong. (If you don’t have CWM, you may want to install Litening ROM first, its easy to install and will give you CWM.)
6. Do in sequence:
– Wipe Data / Factory Reset
– Wipe Cache
– Wipe Dalvik Cache (under Advance)
– Install CM9 zip
– Install GApps 7.1 zip (Optional)
– Install FaceUnlock zip (Optional)
– Install GApps Fixer zip (Required if you installed GApps 7.1 zip and/or FaceUnlock zip)
– Reboot and Enjoy
That’s it. Good luck and enjoy your ice cream sandwich! If you have any questions, I’m more than happy to help. Just drop me a comment or email.
Note: The official thread for this is over at XDA but due to circumstance, the thread has been closed. You can still view the thread here. It contains the links to the downloadables, known issues and some FAQs.
I will upload some sample shots from the ICS camera later on as I do not have Bluetooth on my current PC.
